Morning glory seeds should be planted about 1/2 inch (approximately 1.25 cm) deep in the soil. This depth applies whether you are sowing the seeds directly outdoors or starting them indoors in pots or seed trays
. Additional tips for planting morning glory seeds include:
- Scarify the seeds before planting by nicking the seed coat with a knife or rubbing with sandpaper to improve germination
- Soak the seeds in water for 24 hours prior to planting to encourage quicker germination
- Space the seeds 8 to 12 inches apart to allow room for growth when planting outdoors
- Keep the soil moist and maintain a temperature between 60°F to 85°F (15°C to 29°C) for optimal germination
In summary, plant morning glory seeds about 1/2 inch deep, after scarifying and soaking, and maintain warm, moist conditions for best results.
